It looks like we won't have to wait until Breaking Dawn Part 2 hits theaters in November to see R.Pattz and K.Stew hit a carpet together…because sources tell us that Rob will be attending the On the Road screening with Kristen.

Yes, the often private duo will be stepping out publicly, or so we're told by sources in-the-know about the couple's travel plans.

Which means we might just score more pics of the duo than (hopefully) some PDA-packed paparazzi photos of the two at the beach (or on a yacht…or any of the other Cannes hot spots, naturally).

But before you get your horny Robsten knickers in a bunch, the twosome will actually be a trio: Kristen's mom, Jules Stewart, is apparently attending as well!

Maybe it's Jules' way of publicly approving of her daughter and longtime BF? Or is that reading too much into it? We already know the families like each other anyway, so who cares!

But what should be an eyebrow raiser is seeing her sweet, little Stew getting all sexy on the big screen (that Marylou is quite the minx, haven't you heard?). Heck, Kristen delivers a bit of topless action in the trailer for the film.

Guess Jules should be used to it by now though, what with Kristen's IMDb résumé boasting big-screen spots as a stripper and part-time prostitute and a lady-lovin', drugged-out rock star.
